Magnum 360 to 904

There is no B&M flexplate to mount the 904 behind the magnum...there is one for the 727 behind magnum.

you can use a magnum 5.9 flexplate that has the weights on it to get the 904 to work....

only thing...the 904 converter has one lug offsetted...and the magnum flexplate is a symmetrical...one hole on the flexplate where it mounts to the converter will need to be elongated...

you can also check to see if the magnum to 727 flexplate from B&M if it has the same converter bolt circle as the 904 converter you are using..
